Patented Jan. 6,1914.

Application filed March 15, 1913, Serial No. 754,501. Renewed November21, 1913. Serial No. 802,327.

To all whom it may concern:

Be it known that I, DANIEL L. BRAINE, a citizen of the United States,residing at New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in RailSupporting and Fastening Devices, of which the following is aspecification.

This invention relates to improvements in rail supporting and fasteningdevices, 'and has for its object: to provide an improved form ofsupporting and securing means for holding a rail in place.

Another object is to provide means for firmly securing the rail as thesupporting member wears down.

Another object is to provide a construction which will strengthen orreinforce the fastening members against outward bending as a result ofstress, or thrust, imparted to them by the base of a rail.

. Still another object is to provide an improved form of screw spike,which will permit secure retaining of the rail in place as the samewears down the supporting block.

In connection with the construction shown and described in for example,the co-pending application, No. 727,535, filed October 2 1, 1912, I havefound it advisable to provide a fastening means which will permit readyremoval of the rail, without requiring entire withdrawal of the screwspike. I have also found it advisable, in order to comply with someconditions often met with in railroad practice, to provide for thefollowing down of the rail base, a the latter wears into the supportingblock.

These and other objects will be'set forth in the following specificationand accompanying drawings, in which- Figure 1 is a side elevation of mydevice. Fig. 2 is a plan view of the same, showing one of the spikesremoved. Fig. 3 is an end elevation of the same. Fig. 1 is a detailcross-section, showing a spike in elevation. Fig. 5 is a view similar toFig. 4, showing the spike in a different position, after the rail hasworn the block down some distance. Fig. 6 is a perspective of" one of myscrew spike heads. Fig. 7 is a perspective of the metal frame; and Fig.8 is a perspective of the supporting block.

Like numerals refer to like elements throughout the drawings, in which10designates a conventional form of rail having flanged base, 11. 12indicates the usual form of railway tie, upon which is locatedsupporting block 13, of substantially rectangular cross-section, whichmay have the bolting apertures 14 there-through, as shown in Fig. 8.

The metal frame, 15, having the top portlons, 15 15 and sides 15, 15, isadapted to rest on and closely fit the block 13, as shown. The topportions, 15, 15", are spaced apart a distance approximately equal tothe width of the rail base, 11, the latter being adapted to be seatedthere-between, as shown in Fig. 2, for example. The sides 15, 15 of theframe 15, are cut away between the top port-ions 15 and 15", as shown inFig. 7, and are constructed preferably to terminate short of the uppersurface of the tie, 12, when in position as shown in Fig. 3, therebyeliminating the possibility of the crushing or bruising of the tie bythe frame, 15. This construction in general is similar to that shown anddescribed in the abovementioned co-pending application The top portions15*, 15 of the frame, 15, are provided with the spiking apertures orslots, 16, opening into the space between the top portions, as shown inFig. 7. A portion of the metal frame around each of the apertures, 16,is dished out, or cut away, to form a helical surface, as indicated bynumeral 16 These inclined portions, 16 commence flush with the surfaceof the corresponding top portion, at a point approximately halfwayaround the spiking aperture 16in other words, on a line drawn parallelto the sides 15, 15 through the center of the spiking aperture, 16.These inclined surfaces incline downwardly from the point described toapproximately the under side of the corresponding top portion, asclearly shown in Fig. 7, being helically inclined as mentioneddownwardly, in the direction of rotation of the screw fastening members,as will be described later.

20 designates generally the screw spike or fastening member, having thestem 21, provided with the external helical thread, 22. At its upperportion the spike 20 is provided with an approximately circular head,23, convex on top and bottom, and pro vided with the non-circular upperhead, 24:, adapted to be engaged by a wrench, or etc.

A portion of the head, 23, is cut away, as indicated by the numeral, 25,preferably in a plane parallel to the aXis of the spike, 20, for apurpose to be hereinafter described. The thread, 22, has its inceptionor initial point, 22, as indicated at dotted lines in Fig. 6, at a pointin advance of the plane of the cut-off portion, 25, relative to thedirection of rotation thereof, a. 6., when the screw thread '22 as inthe instance shown is a right-handed thread, right-handed rotation willbe necessary to screw the same downwardly, when securing in place, when,as shown, point 22 ofthe thread will lie forwardly of the cut-offportion, 25, for a reason to be described later.

\Vhen assembling my device, the block, 13, is placed upon the tie, 12,and the frame, 15, is super-imposed upon the block, 13, with the spikingapertures or slots 16 in alinement with spiking apertures, 14, in block13. The rail is located upon the block 13 with its base, 11, between thetop portions 15*, 15 of the frame 15, and the entire structure is movedto the desired position, whereupon the spikes, 20, are inserted throughthe spiking apertures and screwed downwardly there-through into the tie,12. By locating the thread, 22, with its initial engaging point, 22*, asshown, I am able when first driving the spike, by placing the cut-01fportion 24 with its plane parallel to the vertical aXis of the rail-web,to screw the same down to adjacent final position, with the said cut-offportion in position as shown by spike 20 Fig. 2. When in this positionthe head, 23, of the spike, will permit removal or placing of the rail,as will be obvious, and further rotation of the spike in the directionindicated by the arrow in Fig. 2 will operate to bring the spike to itsfastening position, as shown by position of spike 20 in Fig. 2; althoughit is not necessary to rotate the same so far over the rail base, unlessit is so desired. v

The under surface of the head, 23-, of the spike, is helically inclined,of a reverse inclination with respect to the thread 22, that is, itcorresponds to the inclination of a lefthanded thread.

The spike is so constructed and arranged that when in the position ofspike 20", Fig. 2, contact will take place along the line of theunder-side of the spike head, 23, at approximately the beginning point'of the dished out portion, 16, of the correspond ing aperture, 16. Thisinclined or cut-out portion, 16*, is preferably in a helical surfacesimilar in inclination to that of the thread 22.

As the rail wears or crushes down upon the block 13, as shown in Fig. 5,the head 2a of the screw spike 20, may be rotated sufliciently to bringthe under surface 'of the head, 23, of the spike again into contact withthe rail flange or base. Theinclination of the portion, 16*, surroundingthe aperture, 16, will permit the under surface of the head, 23, tofollow downwardl there-along, there being a line cont-act.there between,thus providing a strengthening or reinforcing means for the head of thespike to resist any thrust imparted thereto by the rail base. g

By providing a helical under surface to the head, 23, inclined in adirection opposite to that of the plane of the thread, 22, it will beapparent that all but line contact is eliminated between the undersurface of 23 and the metal frame. Furthermore, the under surface of thehead, 23, is enabled to ride up over and upon the rail base, and forcethe same downwardly as the spike is screwed down. This reverseinclination of the under surface of the head operates to enhance theforcing down of the rail base, as will be obvious, so that less rotationof the spike is necessary to maintain the rail-base in position.

If it is desired to remove the rail, all that is necessary is to unscrewthe spikes to the position shown by spike 20 in Fig. 2, when the railmay be removed bodily therefrom without disturbing the location andadjustment of the supporting block and frame, so that when it is desiredto replace the rail a uniform gage is maintained, by virtue of the factthat it does not become necessary to remove the rail supporting andfastening means from engagement with the tie. Furthermore, by locationof the thread, 22, with its initial point 22 slightly in advance of theplane of the cut-away portion, 25, of the head 23,the advance beingpreferably about a quarter of a ti1rnall that is necessary whenoriginally placing the spikes is for the workman to place the same withcut away portion 24 parallel with the web of the rail, whereupon he maytap the, same with a sledge-hammer into place, and then upon screwingthe same down to position as stated above, the head will assume aposition shown by spike 20 in Fig; 2, just previous to contact with themetal frame. This enables the user to get the benefit of the full amountof the adjustment of the spike, as the rail wears down.
